Isn't this intentional? My understanding is that being tapered like this
keeps the plough iron from binding in the groove. It also keeps the arris
of the iron from wasting away the sides of the groove, which is a problem
I've had with Stanley versions: it's really easy to end up with a ragged
groove if you don't keep the handle perfectly vertical.
